Change default value for max_error_count variable.
  Old value :   64
  New Value : 1024

Fix test cases by:
- record new default value for 'max_error_count'
- record extra warnings in result file due to increase in limit
  of warnings by 'max_error_count'
- Set max_error_count to hard coded 64 (old default value) to contain
  number of warnings in the result file
